Wa. Herrmann et al., CHELATING N-HETEROCYCLIC CARBENE LIGANDS IN PALLADIUM-CATALYZED HECK-TYPE REACTIONS, Journal of organometallic chemistry, 557(1), 1998, pp. 93-96
A novel synthesis of palladium complexes with chelating N-heterocyclic
carbene ligands is reported and direct proof is presented by X-ray di
ffraction. These catalyst precursors are efficiently applied in pallad
ium-catalyzed Heck-, Suzuki-and alkyne coupling reactions, demonstrati
ng the versatility of our ligand concept in homogeneous catalysis. (C)
